For copper-cobalt ores, a sulfide concentrate is roasted under controlled conditions to transform most of the cobalt sulfide to a soluble sulfate while minimizing the change of copper and iron to their water-soluble states. The product is leached, the resulting solution is treated to remove copper and iron, and the cobalt is finally recovered by electrolysis.
